Short answer: no, there is nothing in the Constitution that permits Congress or the other states to kick out a state without such state’s consent (heck, one can’t even approve a constitutional amendment getting rid of a state, since one would be reducing such state’s equal representation in the Senate without its consent). So we need to convince Hawaii, Vermont, etc. that they should become independent.
Theoretically, could the entrenched clause in Article 5 be repealed itself?
Larry “Short Bus” Sabato seemed to think so, as he proposed giving the largest few states an extra Senator.
Thank you for the information Goldwater.
